ANN-assisted forecasting of adsorption efficiency to remove heavy metals

Safe, Natural Ways to Remove Heavy Metals and Toxins

The Efficiency of Bio-adsorption of Heavy Metals from Pharmaceutical Effluent by Rumex crispus L. Seed

The programs of managing waste materials in developing countries are often unsatisfactory and the unreasonable disposal of waste is a major issue in the worldwide. The main aim of the current study is to: Assess the applicability of Rumex crispus L. in removing heavy metals from the contaminated wastewater effluent form Pharmaceutical laboratories by bio-adsorption method. The dried R. crispus ...

Adsorption of heavy metals using marine algae

The discharge of heavy metals into aquatic ecosystem has become a matter of concern in South Africa over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. Conventional methods for metal removal such as ion exchange, reverse osmosis, etc. have proven to be expensive. Due to the increasing awareness of ecolog...

Feasibility Study of Using Adsorbent Plants to Remove Heavy Metals from Wastewater of Petrochemical Industry (Razi Case Study of Tehran)

Background & objectives: Since many plants have high efficiency in absorbing heavy elements, the use of phytoremediation is of great importance. The purpose of this study is to identify native plants that absorb heavy metals. Also, the possibility of using them in phytoremediation technology in soils contaminated with heavy metals (around the petrochemical industry of Razi fertilizer in Tehran ...

Adsorption of heavy metals by EPS of activated sludge.

Extracellular polymeric substances (EPSs) were extracted by high-speed centrifugation at 20,000 G for 30 min from an activated sludge treating municipal wastewater. Each gram of sludge, as measured in volatile suspended solids (VSS), contained 7.3 mg of EPS, including 6.5 mg of protein (EPSp) and 0.8 mg of carbohydrate (EPSc). The EPSp had a mean MW of 2.0 x 105; about 18% of EPSp had MW over 5...
